PNEUMATIC-T1123 IOOL.

Specification of Letters Patent.

To all whom it may concern Be it known thee L ALQER'I W. BAILEY? a citizen of the Embed States, residing at Jasper in the county of Lcnmvee and State of Michigan, have invented new and useful. Improvements in Pneumatic-Tire Toois. of which the folio-wing is a. specificeiion.

This invention reiotes "(o pneumatic tire tools, the object vhivv eing to produce particularly r chic and ing tool by means of of u pneumatic tire of the cloncher "hype may he quickly removed from the rim or c vehie-1e wheel the one tool be g also useful for the purpose of replacing; the tire on the wheel rim.

With the above other objects in view, the invention ooiisists in the novel ccnsirnction, combinaoion and arrangement of parts, herein fully descriheci, iliustre'ted enol claimed.

In the accompanying fireivings Figure 1 is a sicie eie-ve'eion oi a portion of a vehicle wheel and pneumatic tire, SllOW ing the improveci tire cool in 1768 upplieci relotion thereto.

Fig. 2 is an enlarged fragmentary section on the line 2-2 of Fig. 1., v i

Fig. 3 is an enlarged fragmentary section on the line of Fig. 1.

F1 4 is a plan view of the cool detached.

Fig. 5 is a cleteil perspec ive view or the prop or spreader.

Fig. 6 is aplan vievv of the tool in its fully folded position.

The improved tooi comprisee e of hen'cl levers 1 each of which is provided he'- tween the encls thereof with a, pivot joint 2 adapting the tool to he compactly iohicrl as shown in 6 in order that it my be placed in a tool box or other small compertmentof a motor vehicle.

The ievers l are provided with ercmvte tire compressing jaws 3 and between the jaws 3 and the levers l, the latter are crossed and connected together by e pivot Under such an arrangement, as the levers 1 e1 moved towercl each other, the jaws 3 are closed upon the tire so as to press the beaded or clenchezportions or" the outer casing inwardly out 01 engageniene with the clenclier flanges of the rim of the vehicle Wheel. When the levers l are moved into close relotion to each oeher they temporarily held in such posieion by ineens of e pivoted loop or yoke 5 carried by one the levers 1 laterally extended. hearing plane or longer arm 8 is brought into engegeme and adapted. to he passed the other lever as shown. in g. of no j a s d carries Piji/Ifilli', the em? mereoi which prevents injury to the side Wells 01. the hire caeinggc Associaied. with the f and. Each oi one of the jaws has adjacent to lip or hooi 10. or said arms 8 is lo so time the hook or positioned at a pivot than the othe:

In conjunction described "i empioy 1;.- ed to be inserted between the rim and the iire at one side of the ietoeiz restcoin prises a tire supporting oortion lL-il'ifi o prob 12 formed ii the lower extremii e' therewith o, nofieh i3 ociapied to tho clencher flange of the vehicie rim. The operation of the tool may scribed as follows. The too is the outer casing of the tire so that Eh; treniit-ies oi"? the jaws 3 will oloseiy apprr the vehicie rini. The levels 1 are then n" towhrci other and the loop or yoke is siippeol over the ends of the lovers hoicl them in e position in which ihe 3 compressing the side walls of the tire, said jaws serving to press clencher heads the tire inwardly out irom onrierthe clenchcr flanges oi Wheel rim. The two handles or levers 1 i. il'he'i'fimloy oiHJI' FBGf e mil he ooservec'i flier one than the ozbher ifh i are now grasped and moved interoliy to one side of the rim uneii the lip or hook 10 of the shorter arm 8 l'ie mijacene side flange of rini. The hnneie or levers l are then moved the opposit direction until the lip or hooi no of ti.

with the flange at the opposite side of the rim. This results in drawing n portion of the tire radially outvmril from the rim the position illustrateii in Fif 1-. The prop or rest 11 is nowinsertczl between the rim anol one close $0 the tool. The tool is then released from the tire and again brought into engagement -with the hire at a point 8' or 10 inches from the previous position. The tire may now be reeclily removed from the rim. The tire may be replaced on the rim by a mere reversal of the operation herein above described. Actual tests have (lemonstrated; that a tire may be remove& from e vehicle whee1 rim in 19' I ed to said jaws and provided afljacent to the free ends thereof with rim engaging hooks, said arm$ being of unequal length and the hooks thereof being located Al; difierent distances from the pivotal connection of said levers.

In testimony whereof I a'lfix my signature.
